Specification of Letters Patent.

Patented Aug. is, 1908.

Application filed April 12, 1907. Serial No. 367,833.

T 0 all whom it may concern:

Be it known that I, HERBERT E. MARsDEN, residing at Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Branders, of which the following is a specification.

My invention which relates to that type of branders employing self heating burners, primarily has for its object to provide a burner of a very simple and effective construction in which the heating mechanism is so arranged and designed as to afford an even distribution of heat over the entire die face of the apparatus, and in which the parts can be easily and quickly removed or taken apart, as conditions may make desirable.

In its generic nature my brander comprises a brand or die section and a base section to which it is removably secured, the die section inclosing a heating chamber in which a fire-proof core of heat retaining material is held. The base section also supports the burner air and gas feeding mechanism.

A combustion space is provided between the die walls and the fire-proof core, the die section also having heat interrupting air passages to enable a more uniform distribution of the heat over the impression or die surfaces of the die section. An air space is also provided below the flre-proof member in the base section to prevent over-heating thereof.

In its more subordinate nature, the invention embodies certain details of construction, combination and arrangement of arts, all of which will be first described in etail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure 1, is a top plan view of one form of my invention. Fig. 2, is a side elevation thereof. Fig. 3, is a central vertical longitudinal section on the line 3-3 of Fig. 1. Fig. 4, is a cross section on the line 44 of Fig. 1. Fig. 5, is a perspective view of the fire-proof core used in connection with the type of my invention shown in Fig. 1. Fig. 6, is a vertical end elevation of the form of my invention shown in Fig. 1. Fig. 7, is a top plan view of another form of my invention. Fig. 8, is a vertical longitudinal section on the line 88 of Fig. 7. Fig. 9, is a perspective view of the fire-proof core used in the form of my invention shown in Fig. 7.

h Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the fig ures, 1 represents the base section which is provided with an internal chamber 1 and is formed with an internal shoulder or seat 1 to receive core 3 of fire-proof material which will be hereinafter again referred to, it being understood that the core 3 seated upon the shoulder 1 will leave an air space between the bottom thereof and the bottom 1 of the base section, ventilating apertures 1 being provided to admit air to the air space, as shown.

In the form of my invention shown in Figs. 1, 2 and 3, of the drawings, the base section 1 is provided with apertured lugs 1 to receive burner fuel pipes 4 which pass through the lugs 1 into the chamber 1 of the base section 1 and will be projected into alining bores 3 in the flre-proof core 3, it being understood that the diameter of the bores 3 is preferably greater than that of the pipes or tubes 4 to allow for a slight air draft.

The pipes 4 are adjustably held in place by set screws 1 which pass through the lugs or bosses 1 as shown.

The base section 1 is provided with an annular flange 1 at its upper edge which flange has its upper surface provided with grooves or undulations 1 to form a passage from the exterior of the brander to the interior thereof, for a purpose which will be presently eX- plained.

The die section 2 comprises a member having a die face 2" and side and end walls 2 which terminate in beveled flange portions 2 to fit under the fixed bevel stops 1 that are removably secured to the base member 1 by screws 1 or otherwise, and the flange 2 is also adapted to be engaged by the locking slide 5, hereinafter again referred to.

The die section 2 is made hollow to provide an internal chamber that cooperates with the chamber 1 a to receive the fire-proof core 3 hereinbefore referred to, and the un der side of the die face 2 is provided with one or more projections 2 wedge-like in cross section to cooperate with the similarly formed depressions 3 of the core 3 a combustion space 2 being provided between the inner walls of the die section 2 and corres 0 early shown in Fig. 3. The combustion ponding adjacent walls of the core 4, as

. lations 1 so that the products of combustion can pass out from the interior of the brander through the grooves 1 to atmosphere.

2 designates apertures which pass through the rojections 2 from one side of the die section to the other and at each end the apertures 2 communicate with the atmosphere whereby to form air passages that serve to break the heat in the center and enable a uniform distribution of heat over the entire die face 2 of the die section in a manner which will be readily understood by reference to the drawings, it being understood, of course, that the location of the apertures 2- is preferably in alinement with the pipes 4.

The air and gas feeding mechanism includes the burner pipe 4 which at its lower end is provided with a horizontal passage 4 that communicates with a bore 4 in the tubular section 4 that is integrally formed with the pipe 4, the bore 4 being closed by a screw plug 4 as shown.

Into the lower opening of the bore 4 the gas pipe 4 is secured by threading or other wise, while the air pipe 4 is similarly secured in the lower end of the bore of the pipes 4, it being understood that the air pipes 4 may be made to merge with a noz- Zle 4 of less diameter than the main portion of the air pipe 4 and of less diameter than the internal diameter of the pipe 4, so that the effect of a Bunsen flame may be obtained.

The adjustability of the pipe 4 within the lug 1 permits of the flame being directed onto the depressions 3 in such a manner as to obtain a maximum heating effect.

In order to removably hold the die section 2 to the base section, in addition to the fiXed bevels 1 I provide on the opposite side, the slide 5 hereinbefore referred to, which has beveled fingers 5 to engage the bevels 2 and lock the die sections to the base section. The slide 5 operates between a pair of bevel guide plates 5 that are removably secured to the base section by screws 5 or otherwise, and the slide 5 is locked from movement to hold the die and base sections together by a mechanism now to be described. This mechanism comprises a lever 6 which is fulcrumed at 6 to the slide 5 and is also fulcrumed at 6 between a pair of lugs l of the base section 1.

7 designates a relatively fixed wedge removably secured to the base section by screws or bolts 7 a and the fixed wedge 7 cooperates with the slidingwedgeS carried by the lever 6 the wedge 8 being secured to the lever 6 by straps 8 that pass around the lever and being held in its adjusted positions by a set screw 8 as shown, the wedge 8 being limited in its movement along the lever 6 by a stop 6 on the lever.

WVhen the parts are in the position shown in full lines in Fig. 4, the slide 5 is locked and the die section and base section are firmly secured together and when the wedge 8 is released and permitted to fall downwardly, as shown in Fig. 4, then the lever 6 may be swung to the position shown in dotted lines in Fig. 4, to withdraw the slide 5 from en gagement with the die section which can then be lifted off the base section and the 'core 3 removed therefrom, if desired.

In Figs. 6 to 9 inclusive I have shown a slightly modified form of. my invention in which the apparatus is adapted to be used with a single burner mechanism instead of a double burner mechanism as shown in the other figures of the drawings, and in which the burner is of the round brand type instead of the rectangular form as shown in the other figures of the drawings. Also in the form shown in the latter figure instead of using a plurality of bevel plates 1 a single long plate may be used, if desired, the locking arrangement being essentially the same. In this form of my invention, the air space between the core 3 and the base 1 may be of lesser depth than in the form shown in Figs. 1 to 4 inclusive. In this form of my invention the lug 1 is provided with a pocket 9 and an in ternal wall 9 having a small bore so that the flame may be lighted at and begin in the pocket 9 otherwise this form of my invention is essentially the same as that shown in the remaining figures of the drawings.

From'the foregoing description taken in connection with the accompanying drawings it is thought the complete construction, operation and many advantages of my invention will be readily understood by those skilled in the art to which my invention appertains and I desire it understood that numerous slight changes in the detail construction, combination and arrangement of parts may be made without departing from the spirit of the invention or the scope ofthe appended claims.
